如何确定 MacOS 上货币符号位于数字的左侧还是右侧

如何在 Mac Carbon 项目中使用 CFLocale / CFNumberFormatter 确定货币符号应该位于数字的左侧还是右侧？

我需要与电子表格应用程序交互，该应用程序要求我传递数字、货币符号、货币符号位置和填充，而不是使用 CFNumberFormatter 创建的 CStringRef。

CFLocaleRef currentLocale = CFLocaleCopyCurrent();
CFTypeRef currencySymbol = CFLocaleGetValue (currentLocale, kCFLocaleCurrencySymbol);

为我提供字符串形式的货币符号。但我不知道如何确定货币符号的位置......

How do I determine if the currency symbol is supposed to be on the left or right of a number using CFLocale / CFNumberFormatter in a Mac Carbon project?

I need to interface with a spreadsheet application which requires me to pass a number, currency symbol, currency symbol location and padding instead of a CStringRef created with CFNumberFormatter.

CFLocaleRef currentLocale = CFLocaleCopyCurrent();
CFTypeRef currencySymbol = CFLocaleGetValue (currentLocale, kCFLocaleCurrencySymbol);

provides me with the currency symbol as a string. But I'm lost on how to determine the position of the currency symbol...

作为解决方法，我已开始创建一个表示货币值的字符串，并通过搜索该字符串来确定货币符号的位置，但这对我来说确实看起来很可疑。

    CFNumberFormatterRef numberFormatter = CFNumberFormatterCreate(kCFAllocatorDefault, CFLocaleCopyCurrent(), kCFNumberFormatterCurrencyStyle);
    double someNumber = 0;
    CFStringRef asString = CFNumberFormatterCreateStringWithValue(kCFAllocatorDefault, numberFormatter, kCFNumberDoubleType, &someNumber);

...

随意用卷起的报纸打我，告诉我真正的答案...

As a workaround, I have started to create a string representing a currency value and determining the position of the currency symbol by searching the string, but this sure looks fishy to me.

    CFNumberFormatterRef numberFormatter = CFNumberFormatterCreate(kCFAllocatorDefault, CFLocaleCopyCurrent(), kCFNumberFormatterCurrencyStyle);
    double someNumber = 0;
    CFStringRef asString = CFNumberFormatterCreateStringWithValue(kCFAllocatorDefault, numberFormatter, kCFNumberDoubleType, &someNumber);

...

Feel free to hit me with a rolled-up newspaper and tell me the real answer...
